The infection of primary teeth occurs by caries or trauma. But, if it is not treated on time, the complication may occur such as enamel hypoplasia, discoloration, impaction, displacement and dilaceration of permanent successors. The periapical lesion on primary tooth could displace the permanent successors in any direction. Treatment options of displaced tooth are observation after extracting the primary teeth, surgical exposure, orthodontic traction, transplantation and extraction. In these cases, displacement of permanent central incisor caused by the periapical lesion of primary teeth was observed. The spontaneous eruption after extraction of primary teeth was expected considering degree of displacement, development of root and direction of eruption. This case report shows spontaneous eruption of displaced permanent tooth germ was achieved with periodic examination after extraction of primary teeth.

본 연구는 성장 중인 부정교합 환자의 진단이나 치료계획의 수립,치료방법 및 시기,예후 등을 결정하는데 중요한 판단 지침이 되는 치아 석회화 단계와 경추 및 수완부골 성숙도간의 연관성을 규명하여 개인의 보다 정확하고 효율적인 사춘기 성장 정도를 평가하기 위해 시행하였다. 전신 질환이 없고 교정 치료 경험이 없는 7-16세의 여아 154명,남아 179 명,총 333명의 파노라마 방사선사진,측모 두부규격 방사선사진,수완부 방사선사진을 분석하여 평가하였다. 연구 결과,파노라마 방사선사진의 치아 석회화 단계를 통하여 사춘기 성장 정도를 평가하는 것은 부정교합 환자의 진단 및 치료계획을 수립하는데 임상적으로 유용한 정보를 제공할 것으로 판단되었다. The purpose of this study was to investigate the relationship between the stages of calcification of various teeth and skeletal maturity stages among Korean individuals. The study subjects consisted 154 female and 179 male ranging from 7 years to 16 years of age. A total of 333 hand-wrist, cephalo-lateral and panoramic radiographs were obtained and analyzed. The tooth development of the mandibular canines, first, second premolars, and second molars were assessed according to the Dermijian' s system. Skeletal maturity stages were determined from hand-wrist radiographs by using the SMI system and cephalo-lateral radiographs by using the CVMS, respectively. The results were as follows 1. The mean ages of each stage of skeletal maturity were consistently younger in female subjects. 2. There was a high correlation between skeletal maturity of hand-wrist and cervical vertebrae in the both sexes. 3. There was a high correlation between skeletal maturity and dental calcification stage of mandibular canines, first premolar, second premolars, and second molar. 4. The mandibular second molar was tooth showing the highest correlation. 5. Percent distributions of the relationship between calcification stages of individual teeth and stages of skeletal maturity were obtained in both sexes. In summary, this suggests that tooth calcification stages from panoramic radiographs might be clinically useful as a maturity indicator of the pubertal growth period.

강길전,오영균 충남대학교 의과대학 의학연구소 2002 충남의대잡지 Vol.29 No.2

The effect of tibolone, a synthetic steroid with tissue-specific activity, on quality of life in healthy postmenopausal women was studied. A total of 55 women were randomised to 2.5 ㎎ tibolone or to a calcium drug daily for 12 months. Quality of life was assessed by the Blumel method. Information on the occurrence of climacteric complaints and incidences of side effects were also gathered. Compared to baseline values. the tibolone group significantly improved on four out of six domains. including emotional disorder, energy reduction. physical mobility, and social isolation. However. the domains of sleep disorder and pain did not improve. This effect was not a placebo effect in comparison with the control group. The occurrence of hot flushes and nightly sweats was significantly- lower in the tibolone group compared to the control group after 12 months of treatment. Throughout the study period only a few women in the study group and the control group were observed. This did not cause a significant problem. Tibolone can improve the guality of life in postmenopausal women. but the exact mechanism remain to be resolved.

실시간 홀로그래픽 간섭법을 이용한 압력기용기의 내부결함 측정법

姜永準,羅義均 全北大學校 1995 論文集 Vol.40 No.-

Conventional measurement methods using ultrasonic wave or x-ray, eddy current for non-destructive testing(NDT) in nuclear power plants and other industrial plants have been performed as the method of contact with objects to be inspected. With this reason these methods have been taken relatively much time and the inspected area is limited by the location of probe or film. But holographic interferometry which is a non-contact optical measurement method using a coherent light source has an advantage that the quantitative measurement can be performed at a time. In this paper a new method using realtime golographic interferometry and image processing for detecting internal flaws of pressure vessels is presented.

김정균,강영미,엄광식,고영민,김태영 경상대학교 농업생명과학연구원 2003 농업생명과학연구 Vol.37 No.4

한약재로 많이 이용되고 있는 목통, 삼릉 및 치자의 항산화활성과 항균활성 정도를 검토하기 위해 한약재를 물, 70% methanol(MeOH) 및 100% MeOH로 추출한 후 각 추출물의 페놀화합물함량, 전자공여능, hydroxy radical 소거효과, reducing power 및 항균활성시험을 하였다. 그 결과 실험에 사용한 3가지 한약재 모두 항산화효과와 항균활성이 뛰어났으며, 특히 목통 70% MeOH 추출물이 그 효과가 가장 컸으며 다음이 100% MeOH, 물추출물 순이었다. Antioxidant activity and antimicrobial activity of medicinal plants extracts from 3 edible or medicinal plant were examined. The extracts from Akebia quinate Decaisne, Scirusfluviatilis A. Gray, Gardenia jasminoides for. grandiflora Makino showed comparatively strong antioxidative activity on test. Electron donatating abilities and hydroxy radical scavenging ablities of 70% methanol, 100% methanol extracts were higher than thoes of water extracts. Some extracts of medicinal plants showed antimicrobial effect, especially, the extracts showed antimicrobial effect in the 70% methanol higher than other extracts.

The lower leaves shading in upper leaves is unknown to be reduced significantly due to the early differentiation of flower-bud by dark treatment of leaves when growing perilla for harvesting the leaves in the greenhouse during the winter. This study analyzed the effect of dark treatment of leaves on the growth and regulation of flowering, which are closely related with differentiation of flower and amount of leaves. One leaf and 3 leaves per plant were dark treated for 0, 5, 10 days. Plant hight was reduced in 3 leaves treatment, but there was no difference in 1 leaf treatment. Stem diameter was reduced in both 1 leaf and 3 leaves treatments, which was more significant in 3 leaves treatment. Leaf area was reduced when 1 leaf was treated for 10 days, but there was no difference when 1 leaf was treated for 5 days. When 3 leaves were treated, leaf area was no difference between treatments. However, leaf area which 3 leaves were treated was reduced more significantly than that 1 leaf was treated. Seed weight was remarkably decreased when 1 leaf was treated for 10 days, and it was decreased when 3 leaves were treated for more than 5 days.

Extraction charaxteristics of hazardous components were investigated by anticorrosive sand. The hazardours components for anticorrosive sand were not exceeded limited level of groundwater quality. The COD concentration of waste-molding sand showed remarkable difference by molding factory, which was relatively high level. The quantity of corrosion for metalic pipe after lapse of ll month increased in the order of the following sample: sand>soils>waste molding sand. However, anticorrosive sand did not showed corrosion, it was observed that anticorrosive sand one of the the best material used for anticorrosive metalic pipe.

조대술에 의한 하마종의 치료

강동균,황경문,김은정,김현정,김영진,남순현 大韓小兒齒科學會 2006 大韓小兒齒科學會誌 Vol.33 No.1

하마종은 구강저에 발생하는 점액 남종으로 주로 설하선과 관련된다. 즉, 하마종은 설하선 분비도관의 파열로 인하여 타액이 분비도관에서 빠져나와 주위의 연조직 내에 저류됨으로써 발생하는 가성 낭으로 정의 되며, 원인은 설하선 도관의 파열이나 폐색이다. 하마종의 임상소견은 청색의 투명한 종창이 구강저의 소대를 중심으로 편측으로 발생하며, 무통성이며, 촉진시 파동성을 나타낸다. 조직소견은 결합 조직 내 와동이 형성되지만, 낭 벽은 상피세포가 아닌 육아조직으로 구성되는 가성 낭을 관찰할 수 있다. 하마종의 첫 번째 치료법으로는 하마종의 내벽이 구강점막의 일부가 되도록 만들어 주는 조대술을 고려할 수 있다. 본 증례는 특징적인 하마종의 임상소견을 보이는 환아에게 gauze-packing등을 동반한 조대술을 이용하여 치료한 증례로써 양호한 치료결과를 보여 보고하고자 한다. Ranula is a mucocele which occurs at the mouth floor and mostly related to sublingual gland. In other words ranula is definded as a pseudocyst which occurs as the secretion duct of sublingual gland is destructed there as the saliva from the the secretion duct flows out and retention in the soft tissue. The cause of ranula is destruction or obstruction of the duct. The clinical findings of ranula is a painless, unilateral bluish transparent swelling around the frenum and shows fluctuation when palpated. Histological finding represent a formation of cavity inside the connective tissue. but a pseudo-cyst can be seen which the wall of the cyst is composed of granulation tissue rather than epithelial cells. The first treatment of ranula can be considered as marsupialization. which induces the inner wall of the Ranula to be a part of oral mucosa. This case report shows a treatment of marsupialization with gauze packing in a young patient representing a clinical finding of characteristic ranula.
